Magento saves a wrong order total amount and put the order in Subspected Fraud

Question

I've a problem in the order resume when a user is applying a discount code.

In fact the subtotal is 68 + 8 (shipment) and - 6.80 (discount code) = €69.2 and not €76.0 like what's written in the page.

The payment is made with paypal and the total is correct (€69.2) but magento is putting the order in Subspected Fraud - IPN "Completed". Order is suspended as its capture amount 69,20 € is suspected to be fraudulent.

Actually the problem is happening with any discount code. How can I solve this problem?

Answer 1

Are you by any chance running this on PHP7?

If so, you might be looking at error due to order in which totals are calculated. If so, please refer to this.

Answer 2

Check the setting :

Admin->System->Configuration->Sales->Tax->Calculation Setting->Tax Calculation Method Based On

Change this setting as on Total.

Also I think you are not updating grand total and base grand total when applying custom discount programmatically.

You have to update these 2 values when calculating discount.

Try this:-

Replace the following in Mage_Paypal_Model_Hostedpro_Request

protected function _getOrderData(Mage_Sales_Model_Order $order)

     {
                $request = array(
                    'subtotal'      => $this->_formatPrice($order->getBaseSubtotal()),
                    'tax'           => $this->_formatPrice($order->getBaseTaxAmount()),
                    'shipping'      => $this->_formatPrice($order->getBaseShippingAmount()),
                    'invoice'       => $order->getIncrementId(),
                    'address_override' => 'true',
                    'currency_code'    => $order->getBaseCurrencyCode(),
                    'buyer_email'      => $order->getCustomerEmail(),
                    'discount'         => $this->_formatPrice(
                        $order->getBaseGiftCardsAmount()
                        + abs($order->getBaseDiscountAmount())
                        + $order->getBaseCustomerBalanceAmount()
                    ),
                );

with this

protected function _getOrderData(Mage_Sales_Model_Order $order)
    {
        $request = array(
            'subtotal'      => $this->_formatPrice($order->getBaseGrandTotal()),
            'invoice'       => $order->getIncrementId(),
            'address_override' => 'true',
            'currency_code'    => $order->getBaseCurrencyCode(),
            'buyer_email'      => $order->getCustomerEmail(),
            ),
        );
